Some of these embossed papers have a color difference between a flat portion and a concave portion for the purpose of enhancing the visual effect or differentiating the embossed paper. As a method of giving the color difference, for example, there is a method in which ink is applied after forming a flat portion and a concave portion, and thereafter, the ink is wiped so that the ink remains only in the concave portion. Further, depending on the material, the concave portion where the mold is strongly pressed may be crushed and discolored, and therefore, this is utilized. However, these methods have problems such as complicated steps and difficulty in controlling the color.

[0008] Thus, in the present invention, the coating layer contains plastic particles. Since the particles are in the form of particles, when the coating layer is formed, voids are generated between the particles, and light is irregularly reflected to form a white and opaque structure. When a certain amount or more of heat is applied to this layer, the particles are melted, the voids between the particles are reduced, and irregular reflection of light is reduced, so that the transparency of the coating layer is increased.
Also, by applying pressure, the coating layer is crushed, voids between particles are reduced, and irregular reflection of light is reduced, so that the transparency of the coating layer is increased. Therefore, the transparency of the coating layer can be increased by the heat and pressure treatment. Further, in a convex portion of a roll or a mold used for the heat and pressure treatment, that is, in a concave portion of embossed paper, a greater pressure is applied than in a flat portion, so that the degree of transparency is large. As a result, in the embossed paper of the present invention, the color of the base material is more clearly expressed in the concave portions than in the flat portions, and the engraved roll and the pattern of the mold are reproduced in color in synchronization with the shape.

In the present invention, since both the action of heat and the action of pressure are used, it is possible to easily and surely make the coating layer transparent and to make the color clear. Further, since the actions acting on the flat portion and the concave portion are not the same, it is possible to appropriately adjust the difference in the degree of transparency between the flat portion and the concave portion, and to finely control the color difference between the flat portion and the concave portion. it can. Further, the coating layer in the present invention has effects such as protection of the surface of the base material and improvement of gloss, and further, improvement of color density and gloss of a printed portion.

The colored substrate of the present invention (including the substrate in the raw material color) is a substrate that can be visually sensed to be a color different from the color of the coating layer after the heat and pressure treatment. It is. This is because even if a difference in the transparency of the coating layer between the flat portion and the concave portion occurs after the heat and pressure treatment, if the colors of the coating layer and the base material are the same, there is no difference in color in appearance. The color of the coating layer is not limited as long as it is a base material that can be visually sensed as being different from the color of the coating layer. However, the coating layer often has a white or whitish color. Is often preferred to a color other than white. The coating layer may be white or colored.

If the temperature exceeds 130 ° C., the temperature required for the roll and the mold of the lithographic press to increase the transparency becomes too high, which causes a problem in processing. Further, the shape of the particles is not limited. When the layer is formed, some voids occur between the particles,
Any shape can be used as long as it causes irregular reflection of light when the layer is irradiated with light.
